Battery Issue..Please help..

I am using the Sensation on stock ROM..and about two weeks ago got a minor update to it (which provided the power saver option on the quick settings menu)..And since about a week now, my phone takes an elongated time to charge..previously, it took only about 2 hours to fully charge the phone, but now it takes more than 3 hours..plus, it takes only about 1.5 hours to charge from 0% to 80%, but afterwards, it takes more than another 1.5 hours to charge the remaining 20%..but after about 90% it literally stops charging further, no matter how long I keep the phone plugged to the charger..But when I restart the phone at that time, it indicates the battery level as 100%..
Does anyone else has the similar kind of problem? And can anyone please suggest me what to do? Is it a problem with my battery or is it a software issue? Please help me..
Thanks in advance..

Perhaps you need to reset the "stats" of the battery ?
Charge the device to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings » About device » Status » Battery Level = Full.)
Boot to recovery mode and delete the battery stats
NOTE: To have the most accurate of battery stats, reboot the device immediately after wiping the battery stats and wait for CyanogenMod to boot completely to the desktop. Once your entire boot is done and you have full access to the device, go ahead and pull the charger and continue with this troubleshooter.
Do not charge the device until after draining the battery completely, resulting in it automatically shutting off.
Recharge the device completely and then use as you normally would.

I am also facing almost same issues with battery. The phone charges very fast from 0% to around 75%. The remaining 75% to 100% takes a long time. But it does reach 100%. It doesnt stop before. And if I reboot the phone when charge is 80% or 90% it will immediately show 100% on reboot. So which value was correct? Before or after reboot?
Another thing is during the day when I am using the phone and the battery is at any particluar level for ex. 45%. And I reboot the phone for any reason. After rebooting the battery level is shown as increased to 50% or any other value. How does battery increase on rebooting the phone?
My theory is that HTC Sensation is unable to read battery level accurately and therefore such incorrect values are reported. BTW this happens on both the stock battery and my current Anker 1900mAh battery.

Hey mate, did this error started to occur after you updated your phone or was it there prior to the update as well?

This situation was there before the update too. Maybe some experts here will give their opinion on this.

[Q] Power Issue.. Please Help!

Hi all,
There's this problem with my phone that everytime I charge it, it takes an elongated time to do so. This issue first emerged when I was on stock GB after a minor OTA update which added the power saver toggle to the quick settings menu..The problem is that it takes about 4-5 hours to fully charge the phone, and if I rebooted in the middle of charging when it's about 70% or 80%, it suddenly shows that the phone is fully charged, and the indicator becomes green! But afterwards the battery drains as quickly!
Now I have S-Off and using ARHD 6.6.3 ROM, but it seems the problem persists ..I wiped battery stats as soon as I flashed the ROM as well..Although it's not a problem I cannot live with, it's annoying enough when it happens.
Can someone please help me? And suggest me what to do?

its common thing...the battery calibration is not proper that's all...
also you need to wipe stats once you charge your phone to 100%
then battery will try to calibrate ...and after 3-4 full complete cycles (100-0 and 0-100)
the battery will settle..
the battery drain will be there ...whenever you flash a rom or flash a kernel....battery only settles atleast after 2 full cycles
EDIT: also download currentwidget from market..as the name says its a widget..so you will see it in widgets once you installed it...this will give you more proper reading of battery...when you plug your phone to charge...and when current widget reads 0mah then your battery is charged completely...(it might take a long time to read 0mah...but charge it until you see 0mah)..then wipe the battery stats...so after this battery calibration will be proper
Also the sudden jump of battery percentage is due to improper battery calibration
so dont worry you got no problem

So
I read somewhere that you are not supposed to let the phone go to zero because it could cause your phone to not power back on anymore..is this fact. I couldn't find where I read it to back and read again. Mine has been doing some weird things as well...the led turns green before it is 100% and it goes from 100% and drops to like 89% out of no where.

when i meant 100%-0% means until your phone turns off due to less power..it might not(or won't be) be 0% then
as i told you that kind of jumps are common ...in my case it went to 60% to 100% when i rebooted ...also the dropping used to be in large scale too

[Q] Roms and battery life - Unable to start phone

Hi,
I have recently tried out a few ROMs with my Nexus S to try to get better battery life. I tried CodeName Android and then figured I would try Slim ICS afterwards. I completely wiped everything and installed Slim ICS.
I have observed the following:
- Battery was ~40% when I installed Slim ICS
- I used it until the battery depleted
- Plugged phone into the wall charger
- Started the phone shortly afterwards (~25 minutes) and it says battery is 100% and then the phone randomly shut off
- Phone has been plugged into the wall charger and when I try to start it now sometimes it boots completely and then shuts off. Other times it just shuts off before it finishes booting up. The few times it does fully boot up, it says the battery is 100%
I've read through many postings about calibration but at this point I am not even able to fully turn on the phone even when its plugged into the wall.
Is this expected or is something else going on? I've never seen anything like this when I had the stock ICS. Why would erroneously report 100% but then not even let me fully turn on the phone? Thanks!

Maybe a bad battery?

Battery is fine. I ended up letting it charge a few hours and it now fully boots up and battery is almost fully charged now.
Whats strange is at times, when the battery was close to empty, when turned off and plugged into the wall, it showed the battery as being completely charged so I don't think it was charging. I had never observed this behavior with the stock ICS.

If it happens again I would suggest taking it to a sprint repair

same problem
Even I have faced the same problem whenever I reboot keeping my pfone charging,
This is very normal,
just let the battery drain completely and next time charge it till 100% it will work perfectly,
It happens with me whenever I install new rom.
basically the battery indicator shows incorrect status also battery will drain very quickly later but once you finish installation just let your phone charge for 3 hours . Problem will get solved

Also, you could try clearing the battery stats in clockwork mod recovery

Thanks. So it sounds like its more of a generic issue with ROMS in general as I never observed this before putting on a custom ROM.

Moto Maxx never going below 15% battery

My Moto Maxx is never going below 15% battery for quite some time.
I was running CM 12.1 before and I am running the CM 13.0 preview now.
The problem now seems much worse.
This could be my battery dying?

Wait its not going below 15% or above 15%? Also, did you flash the ROM with a clean wipe (no dirty flash)?
Another thing to note is that the CM 13.0 Build is a "PREVIEW" which means that there are a TON of bugs in there. I would advise you go back to CM 12.1 for the time being.

It is never going below 15%.
On CM12.1 it also happened.
When it reaches 15% percent, the phone shuts down and needs to be charged.
After sometime charging, it displays the battery as above 15% and I can turn it on again.

Mine had always done that at 5 percent. Here lately it's closer to 7 percent.

I'm on original 5.0.2 and also facing that issue... I've heard onde it's related to the use of non original chargers, or even QI chargers... Never got rid of it, even after a full wipe/factory reset...

I've had this problem too and made a post over in the Droid Turbo forums but no one ever replied..
At least I'm not the only one that has this problem.

Yeah I've always had this issue between 5-8% on my three Turbos. Stock Rom and other flavors. They all shut the phone down around there.

Solved the problem with this app: https://play.google.com/store/apps/details?id=com.newagetools.batdoc&hl=pt_BR
Now my battery goes down to 1% again, yahoo!!!!

how can that app fix it?? i would think its a placebo effect as i see dificult for an app to read or fix battery info...
maybe it locks out the bad parts (like an old chkdsk on a HD)
anyway i will tryit if i see it tries to go rogue with the Ads it Dies..

Batteries in laptops and phones have a file that keeps track of battery life. They use this to estimate percentage.

still having this issue

I have the same problem. It started as shutting down at %5, then %7, now it's %15 shuts down.

The same thing on my XT1254. It shuts down near 5%, I will try to charge it with my old i9505 charger, it could be a problem related to TurboCharger.

Hello guys,
My girlfriend's phone had this issue some months ago, what I did in order to fix this issue was:
1) Let the battery drain until phone shutdown. (try to turn on again until you cannot)
2) Fully charge with an original Motorola charger (phone turned off)
3) When it reached 100%, turn on the phone but enter in the fastboot mode and wipe caches
4) Uses the phone normally and let reaches 0%.
Making these steps, the battery back to have a "normal" behaviour

I´ll perform these steps, thank you

Although you see the battery as percentage, the operating system does not see it that way. It uses lower limit voltage of the battery to shut down the device in order to extend battery life. Batteries do not like to get and stay deep discharged (below low level voltage)...if you do this frequently, you will severely hamper your battery's life.

galaxy j7 battery problem

i think my phone has some serious problems and i'm wondering if it's the battery dying or a short circuit
when i plug it on a charger while of it shows a normal charging image but how it switches from one animation to the other so i can see the status of battery percent it's like a short on the screen happened
it chargers to 100 but when i switch it on it shows mybe 95 but never 100 and if i connect it to a charger to get to 100 it only decreases
it gets warm now days which did not happen and it like drains 50% overnight which is obviously not normal. these two days the battery life is like 4 hours with internet wich with j7's battery it should not happen. if i switch it off and then on again i loose like 20% of battery and if that is all i had i get 0% and the phone doesnt switch on. the phone never had contact with water . it's been 4 days since this started and it happened all of sudden like today my phone stays up to two days at most and i just woke up it barely finishes a day without data and with power saving mode
i'm sure it's not about background apps or any activities because i hard reset it already and i don't have any app. and it's not about wifi or sync or poor network i tried all that. i did everything it didnt help. i could buy a new battery but i'm scared it might be a short because i don't think a battery can just die in one night like this.
can anyone help me with this or it's nothing serious and i have to change the battery
